Filed: 1990-05-17
Abstract: PURPOSE:To make a fitting jig light in weight and to reduce cost by coating a carbon sliding plate for a pantograph for a railway with copper and joining the copper coated surface to an Al-based material by a joining means at a low temp. CONSTITUTION:A carbon sliding plate 1 with a cupper coating layer 1-1 formed oh the entire surface by copper plating is joined to a current collector boat 2 made of an Al-based material with a brazing layer 3 in-between. Since the copper coating layer 1-1 improves the wettability of a carbon-metal composite material, the carbon sliding plate 1 can be joined to the Al-based material 2 by a joining means at a low temp. of <=450 deg.C such as brazing. The plate 1 is not affected by heat, cracking can be prevented and high bonding strength is obtd., accordingly the plate 1 can directly be fitted to the boat 2.

Filed: 1993-05-31
Abstract: PURPOSE: To provide a mask which has a 1st patterned reflecting coating on its front surface and a patterned radiation shield layer such as a 2nd patterned dielectric coating with high reflectivity on its back surface and to provide its manufacture. CONSTITUTION: This mask has the 1st patterned reflective coating 14 on its front surface and the patterned radiation shield layer such as the 2nd patterned dielectric coating with high reflectivity on the back surface.
